Question:

I am looking for a 6 pole to 7 pole adapter. The 6 round is on the truck side and the 7 pole is on the Commercial trailer side. Can you point me in the right direction?

Expert Reply:

I have a couple options as there is not one adapter from a 6-pin round vehicle connector to a 7-pin round commercial trailer connector.

The first will combine a Adapter 6-Pole to 7-Pole Trailer Wiring Adapter # 47435 and a Pollak Trailer Connector Adapter # PK12727 to adapt your connections.

Or you can wire in a Pollak 6-Pole, Round Pin, Trailer Wiring Connector # PK11604 to a Pollak Heavy-Duty, 7-Pole, Round Pin Trailer Wiring Socket # PK11720. This will create your own wiring adapter. You will need to source the correct length wiring from your local automotive or hardware store for the adapter. I have included wiring images for both connectors.
